However, it has also been argued that STDP alone is not enough to maintain a balanced network, as repeated high-frequency stimulus could trigger a continuous chain of LTP which infinitely increases the weights of the network ([1]}). In order to attempt to counter this, we introduced both inhibitory neurons, as well as inhibitory plasticity, iSTDP, inspired by the implementation in [2]}. The idea is that an inhibitory neuron should increase its firing to a post-synaptic excitatory neuron if that excitatory neuron fires too often.
